Wearing a bright pink baseball cap, Roberts, who's had eight days of intense chemotherapy during her 11 days in the hospital, said: "This journey is as much about the mind as it is the body. Your thoughts … are so powerful. You’ve got to change the way you think in order to change the way you feel. And let me just say this lastly, I feel the love and I thank you for it. Thank you."

During her hospital stay, Roberts has been surrounded by friends and family, said her co-anchor, George Stephanopoulos. Her bone marrow donor was her sister, Sally. Many transplant recipients refer to the day of their transplant as their new birthday.

In addition, Dr. Roboz said that even reading a few emails and sitting up in bed is exhausting for Roberts. Despite this, GMA weatherman Sam Champion, who visited his colleague in the hospital, said, "She is in remarkable spirits."

Throughout the rest of Thursday's broadcast, her co-stars shouted out messages of love to Roberts. Viewers' messages may be sent to her at #teamrobin.
